Ethernet Communication Module DVPEN01-SL
DVP-PLC Operation Manual
13
When the CR value is set as “0”
16-bit mode; when the CR value is set as “1”
8-bit mode.
CR#112:
MODBUS client Keepalive time-out
Explanations:
CR#112 is the TCP Keepalive timeout for MODBUS TCP connection. (Unit: Second)
Default: 30s
If the connection idle time becomes longer than the keep-alive time-out, DVPEN01-SL will cut off the idle connection.
CR#114:
MODBUS TCP timeout
Explanations:
Setting the communication time-out (in ms) for MODBUS TCP mode
CR#115:
MODBUS TCP trigger
Explanations:
When the CR value is set as “1”, MODBUS TCP will be triggered. After the data transmission is completed in MODBUS
TCP mode, the CR value will automatically be reset to “0”. Please trigger by differential instructions.
CR#116:
MODBUS TCP status
Explanations:
Displaying the current communication status of MODBUS TCP mode
When the CR value is set as”0”
the data have not yet been received; when the CR value is set as “1”
the data
exchange is in progress; when the CR value is set as “2”
the data exchange is successful; when the CR value is set
as “3”
the data exchange fails.
CR value
Data exchange status
0
The data have not been received.
1
The data exchange is in progress.
2
The data exchange is successful.
3
The data exchange fails.
CR#117~118:
MODBUS TCP destination IP address
Explanations:
Setting the destination IP address in MODBUS TCP mode
See explanations on CR#70 and #71 for more information.
CR#119:
MODBUS TCP data length
Explanations:
Setting the length of communication data in MODBUS TCP mode
Length for 8-bit mode: K1~K100
Length for 16-bit mode: K1~K200.
